Maximum efficiency of a Penning plasma laser on neon

A great number o recent papers were devoted to the investigation or a Penning plasma laser under the conditions or electron-beam and nuclear puinpin,g and to the experimental and theoretical investigations or plasmochemical and radiation processes in the active medium (see , tor example , [1 1 ) . But the question about maximal erriciency o the laser is opened yet and this is the main purpose or the paper.
